CAR-HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent N 0. 461,281, dated October13. 1891. Application filed March '1, 1891. Serial No. 383,754. (Nomodel.)

To all whom it may concern.-

Be it known that I, JOHN Q. C. SEARLE, a citizen of the UnitedSta'tes,residing at Chicago, in the county of Cook and State ofIllinois, have invented new and useful Improvements in Car-HeatingApparatus, of which the following is a specification.

This invention relates to improvements in that class of hot-waterwarming apparatus shownanddescribedinmypatents,No.311,534E, February 3,1885, and No. 340,825, April 27, 1886, in which the water is heated in asingle coil and made to circulate through separate and distinct lines ofpipe on each side of the car and requiring but one expansion-chamber forthe heating apparatus in each car; but owing to the increased size andlength of railway-cars as now constructed it is found desirable thatincreased heating capacity be provided and more hot Water supplied tothe circulating-pipes withou L enlarging theheater.

To this end, therefore, my present invention consists in providing ahot-water warming apparatus comprising a heater, two separate anddistinct heating and circulating passages, a water-uniting fitting, asingle ascending pipe, a combined expansion and waterdividing chamber,two separate descending pipes, circulating-pipes that heat each side ofthe car separately, and two return-pipes for returning the cooled waterto the separate heating and circulating passages from which it started,whereby I am enabled to increase the heating capacity of the apparatusand supply more hotwater to the circulating pipes without enlarging theheater.

The apparatus may also comprise one or more cocks or valves, whereby-aneven circulation and an even temperature can be effected on each side ofthe car, which in a cold day, with a strong wind blowing against oneside of the train of cars, has heretofore made it impossible to warmthat side of the car.

The annexed drawing, illustrating the invention, is a perspective of ahot-water warming apparatus, with the heater in section, showing thecombination of parts,whereby the Water that is heated in two separateand distinct heating and circulating passages is con ducted to thecirculating-pipes that heat each side of the car separately, andafterward by the return-pipes the cooled water is returned to theseparate heating-passages from which it started,

The numeral 1 designates a heater provided with a heating-coil 2 and aseparate heating and circulating passage 3, though any other approvedform of heating device having two separate heating and circulatingpassages will answer to heat the water that warms the car.

After the water has been properly heated it is conducted through afitting 7, a pipe 5,

a combined expansion and water-dividing chamber 6, and two descendingpipes 9 and 12 to the circulating-pipes 10 and 13, that heat each sideof the car separately, and by the pipes 11 and 14 the cooled water maybe returned to the separate heating and circulating passages from whichit started.

It further consists in providing means whereby an even circulation andan even temperature is secured on each side of the car. To obtain thisresult I place in the pipes 11 and 14 a cook or valve, as 19 and20,bymeans of which the circulation may be regulated.

Should the water circulate faster on one to the entire apparatus at onepoint, thereby.

avoiding any necessity of a separate expansion-chamber for each side ofthe car and-the consequent increased attention of the trainmen to seethat each side of the apparatus is safe and in proper condition for use.

From the foregoing description the operation and advantages of thishot-water warm ing apparatus will be obvious.

I do not herein broadly claim the combination of a furnace, a pluralityof independent liquid-heating passages therein, a pluralityofindependent radiators communicating with the liquid-heating passages,and a temperature-equalizing chamber, pipe, or passage communicatingwith the upper ends of the said liquid-heating passages and with theradiators, as such constitutes the subject-matter of my application forLetters Patent filed October 9, 1890, Serial No. 367,565.

Having thus described my present invention, what I claim as new, anddesire to secure by Letters Patent, is

1.,The combination,in a hot-Water Warming apparatus, of a heater, twoseparate and distinct heating and circulating passages, a water-unitingfitting 7, a combined expansion and Water-dividing chamber 6, the pipe5, that connects said Water-uniting fitting with said expansion andWater-dividing chamber, the circulating-pipes 10 and 13, that heat thecar, the pipes 9 and 12, that connect said circulating-pipes with saidexpansion and Waterdividing chamber, and the return-pipes'll and 14,that return the cooled Water to the separate heating and circulatingpassages from which it started.

apparatus, of a heater, two separate and distinct heating andcirculating passages, a water-uniting fitting 7, a combined expansionand water-dividingchamber 6, the pipe 25 5, that connects saidWater-uniting fitting with said expansion and Water-dividing chamber,the circulating-pipes 10 and 13, that heat the car, the pipes 9 and 12,that connect said circulating-pipes with said expansion and Water- 0dividing chamber, and the return-pipes 11 and 14, that return the cooledWater to said heating and circulating passages, said pipes pro videdwith one or more cocks 19 and 20, as and for the purpose specified.

In testimony whereof I have hereunto set my hand and affixed my seal inpresence of tWo subscribing Witnesses.
